When you order this combo, you aren't just getting a tuner - you are getting the tuner and 3 custom tunes that are written specifically for your Mustang and your particular modifications by VMP Tuning.

Increase Your Mod's Potential. From the factory, Ford programs their vehicles to cater to the needs of the daily driver, not the performance enthusiast who adds aftermarket bolt-on modifications in search of more power. That is why a custom tune file is so important, by optimizing the air/fuel ratio, adjusting ignition timing and tweaking variable cam timing, a VMP Tuning Custom Tune will squeeze out the extra power your aftermarket performance mods have to offer.

Application. This Steeda Cold Air Intake and SCT X4 Power Flash Tuner with 3 custom tune files by VMP Tuning is specially designed to fit the 2011-2014 Manual GT Mustang's equipped with the coyote 5.0L 4 valve V8 engine with or without basic bolt-on upgrade modifications such as a Throttle Body and/or Full Exhaust System.

**Please Note: The SCT SF4/X4 Tuner ships blank from AmericanMuscle, the custom tune files will be emailed directly to the end user within 5-7 business days from VMP Tuning.

Word on The Street

On my most recent order from AM I had some challenges with the product installation. The customer service team at AM resolved all of my challenges quickly, efficiently and pleasantly. At all times their customer service team exceeded my expectations. I have pulled all of the other car supplier catalogs from my magazine racks except the American Muscle catalog. From now on my Mustang only rides with American Muscle. Thank you for exceeding my expectations.
